4.7 Hot Addition of PCI Express cards

7. Check whether there is an error in added FC card by MMB Maintenance Wizard.
This step is performed by the field engineer in charge of your system.
For details on the operation of replacement, see step 8 to 11 of ‘Operation for Hot replacement of PCI
Express card by Maintenance Wizard’ in “4.7.2 PCI Express card addition procedure in detail”.
8. Check the version of the firmware
It is required that the firmware version of new FC card is same as that of the FC card which had been
replaced. If the firmware version of new FC card is coincident with that of the FC card which had been
replaced (current firmware version), it is not necessary to update the firmware version of new FC card to
current firmware version.
If the firmware version of new FC card is not coincident with that of the FC card which had been replaced
(current firmware version), update the firmware version of new FC card to current firmware version.
For how to update the firmware version, see Firmware update manual for fibre channel card.
Note
If you cannot confirm the firmware version of the FC card before replacing due to the fault of the FC card,
check the firmware version of the FC card which is same type as the faulty one to update firmware
version.
9. Confirm the incorporation results
The method of confirming is the same as that is performed in the replacement of FC card. See
‘Confirming the FC card incorporation results’ in ‘4.6.3 FC card (Fibre Channel card) replacement
procedure’.
4.7.4 Network card addition procedure
NIC (network card) addition using hot plugging needs specific processing before and after PCI slot power-on
or power-off. Its procedure also includes the common PCI Express card addition procedure.
The procedure describes operations where a single NIC is configured as one interface. It also describes
cases where multiple NICs are bonded together to configure one interface (bonding configuration). For
bonding multiple NIC by using PRIMECLUSTER Global Link Services (GLS), see 'PRIMECLUSTER Global
Link Service Configuration and Administration Guide Redundant Line Control Function' (J2UZ-7781).

NIC addition procedure
This section describes the procedure for hot plugging only a network card.
Note
When adding multiple NICs, be sure to add them one by one. If you do this with multiple cards at the same
time, the correct settings may not be made.
1. Confirm the existing interface names.
To confirm the interface names, execute the following command.
Example: eth0 is the only interface on the NIC.
# /sbin/ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:0E:0C:70:C3:38
